I didnt first time round but then saw this on a website, then when i looked this up on the internet the code that i'm supposed to insert into the file was different on a few different sites?? any idea what im actually supposed to add to the file

Just add what's on that site link I gave you, it worked for me. I didn't even use tinyumbrella.
The. Code is actually an ip address that links to the cydia server, I don't know If they have multiple addresses or If they changed it, but the one on the site is the most updated one and worked for me last week

I to want to do this but I not sure cydia has my shsh on file even though it says it has 4.01 on it's server
because I jailbroke my ip4 a day after 4.02. Came out could cydia make a mistake or do apple keep signing for a few days after?
How can I check

When 4.0.2 came out, apple was still signing for 4.0.1 until a week after. They usually don't do this, but that's what happened. Use tiny umbrella to make sure u have them

the reason that tinyumbrella didn't work for you is that you have to first save the shsh blobs to your computer using tinyumbrella and then start the TSS server (which by the way it edits your host file for you to point back to your own computer), it's a good idea to save the shsh's to your own computer as a precaution in case saurik's server is down and you need to restore

i have an iphone 4 4.0 firmware.It was working perfectly for me but then i installed lockdown application from Cydia and then my phone just stopped working.I can open the applications but they are not working.I want to restore my firmware and installed tiny umberella also and took a ssh back up.I put the phone on
dfu mode But whenever i try to restore the [I] tune gives an error 3179.
Can any one please help
